EDGAR PECKHAM AND EMIL LAASS, OF SYRACUSE, NEIV YORK, ASSIGNORS, BYDIRECT AND MESNE ASSIGNMENTS, TO M. J. PECKHAM, OF SAME CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 354,214, dated December14, 1886.

Application filed March 25, 1886. Serial No. 196,490. (K model.)

To all whom it may concern:

Be it known that we, EDGAR PEOKHAM and EMIL LAASS, of Syracuse, in thecounty of Onondaga, in the State of New York, have invented new anduseful Improvements in Car- Wheels, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention consists in a novel construc- IO tion of a wheel which isperfectly secure and capable of resisting the strain it is subjected towhen in use, and yet adapted to be readily taken apart for repairs orrenewal of its parts.

In the accompanying drawings, Figure 1 is I a longitudinal section of acar-axle provided with our improved wheels. Fig. 2 is a trans versesection on line a: no, Fig. 1, with the de tachable parts of the wheelremoved. Fig. 3 is a transverse section on line y 3 Fig. 1; and

Fig. 4 is a detached face View of the collar, which retains thetreadring on the hub of the wheel.

Similar letters of reference indicate corre sponding parts.

2 A represents acar-axle, which may be either tubular, as shown in theannexed drawings,

or of the usual solid form.

W IV denote the two carwheels embodying our invention, the mostessential feature of which consists of the hub H and the treadringR,detachably connected to said hub. The hub H is designed to bepermanently secured to the axle, and this may be effected either byshrinking it thereon or pressing it on in the 5 same manner ascar-wheels are coinmonl y fixed to the axle. \Ve form this hub with acircumferential rabbet, one of the faces of which is parallel with theaxis of the hub, and serves as a seat, I), for the ring R, which isprovided with a central eye, by which it rests on said seat, the outerperiphery of said ring being formed with the usual flanged tread, t. Theother face of the aforesaid rabbet of the hub stands vertical or radialfrom the axis of the hub, and serves as an abutment,c, against which therear side of the ring R rests. At the front or outer edge of the seat I)the hub H is provided with a circumferential groove, 0, and

with recesses r r in said groove. The end portion of the hub at theoutside of the groove 0 is provided with a collar, 0, which is-of adiameter to allow the central eye of the treadring R to slip over itinplacing said ring on the hub or removing it therefrom.

In the groove 0 is seated removabl y the col- 5 5 lar O, which isprovided with a central eye fitted closely to the interior of saidgroove and provided with projections d d,which enter the recesses 1" r,and thus prevent said collar from turning.

It will be observed that the collar 0 e011- stitutes an abutment at theouter end of the hub, and the ring R and collar 0 are clamped betweenthe two abutments c and a on opposite ends of the hub,and are thussecurely held in their proper position.

In order to permit of applying the collar to the hub and of removing ittherefrom when required, we dividesaid collar diametrically into twoparts and detachably clamp the same together, as shown in Figs. 3 and 4of the drawlngs.

By means of bolts 0 e, passing through the collar 0, ring R, andabutment a, the collar is clamped tightly against the side of the ring R7 5 and the latter is firmly secured on the hub.

hen it is desired to allow the two wheels WV IV to rotate independentlyof each other, we omit the bolts 6 e,and thus allow the treadring R torotate on the hub H. In this case we employ set-screws c e, insertedthrough the outer end of the hub'and bearing with their innerends on thecollar 0, as represented at the righthand end of the axle, (shown inFig. 1 of the drawings,) and this wheel can be made self-lubricating byemploying a tubular axle and securing a dam, n, across the inte- I riorof the tube, at or near the inner end of the l1ub,and closing the end ofthe tube by a screwthreaded plug, at, so as to form a lubricantoreservoir similar to that shown in the patent issued to E. Pecliham,March 10, 1885. Ohannels i, extending from the lubricant'reservoir tothe seat b of the ring R, allow thelubricant.

to flow to said seat. By clamping on opposite sides of the ring Rshieldst t, lapping onto the exterior of the abutment a and collar 0,dust is excluded from the bearings of the said ring on the hub.

It is obvious that this invention is applicable to wheels of ordinaryroad-wagons, and we therefore do not limit the use of our invention tocar-wheels.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the hub H, formed with the seat I), abutment a atthe inner end of the hub, andwthe groove 0 and the collar 0 at the outerend of the hub, the ring R, mounted on said seat, and the collar 0,secured in the groove 0, and bolts for tightening the collar 0 on thering R, substantially as described and shown.

2. The combination of the hub H, formed with the seat 6, abutment a,groove 0, recess r r in said groove, and the collar 0 at the outer endof the hub, the tread-ring R, mounted on said seat, the collar 0, seatedin the groove 0,

and provided with the projections d d, and

bolts for tightening the collar 0 on the ring R, substantially asdescribed and shown.

3. In combination with the tubular axle formed with an internallubricant-reservoir, and provided with lubricating-channels 2', the

hub H,provided with corresponding channels,

hub H,provided with corresponding channels,

and formed with the scat b, abutment a, groove 0, and collar 0, the ringR, mounted on said seat, the collar 0, secured in the groove 0, and theshields t t,secured to opposite sides of the ring R and lapping onto theabutment a and collar 0, substantially as described and shown. Intestimony whereof we have hereunto signed our names and affixed ourseals, in the presence of two attesting witnesses, at Syracuse, in thecounty of Onondaga, in the State of New York, this 18th day of March,1886.
